Yes - good advice for game saves.
I will add some more:-
Always always save your game just before picking the next campaign section. Name it as campaign end "CoastalWaters End etc"
This is a very handy return point.
Every time you progress to a new stage in the campaign - the game loads that section as if it is a new career and then checks and adds your profile.
So - this save point is as good as a new career start
The next most important is the bunker save - save this before you talk to the KMO.
This save point is a good save to change your boat equip (with mods) as the 3d world is re-loaded when you select start patrol
